CVE-2025-4450Network attack vector

Memory corruption via curTime buffer overflow

Published May 9, 2025 · Updated May 9, 2025

Buffer overflow in D-Link DIR-619L 2.04B04 allows remote authenticated users to corrupt memory through the formSetEasy_Wizard curTime argument. Public sources identify the handler and argument but do not disclose the copy operation or destination buffer that fails to enforce bounds. Management-interface access is required, and public sources do not establish whether the corruption causes a crash or attacker-controlled code execution.
